Description

Technical Field

[0001] This utility model relates to the field of hammerhead technology, and more specifically, to a wear-resistant hammerhead for a crusher. Background Technology

[0002] Hammer crushers are commonly used equipment in crushing and sand making production lines. They are widely used for crushing iron ore, sandstone, gypsum, blast furnace slag, coal gangue, lump coal, and other medium-hard ores. The hammers are one of the core components of the hammer crusher. They are arranged on the pins of the crusher rotor and directly strike the material when the crusher is running at high speed. As a result, they are constantly subjected to the combined effects of impact and compression from high-hardness materials, which gradually leads to wear. Therefore, the service life of the hammers is a key factor affecting the working efficiency and operation and maintenance costs of the entire crushing system.

[0003] Among them, the patent with announcement number CN214439605U discloses a new type of wear-resistant hammer for crushers, including a hammer handle, a hammer body is provided on the lower outer surface of the hammer handle, a mounting hole is provided on the front outer surface of the hammer handle, a wear-resistant ring is provided on the inner outer surface of the mounting hole, an anti-wear ring is provided on the front outer surface of the hammer handle, a hammer core is provided on the lower outer surface of the hammer body, a hammer head body is provided on the side outer surface of the hammer core, a limit hole is provided on the side outer surface of both the hammer head body and the hammer core, and a positioning hole is provided on the front outer surface of both the hammer head body and the hammer core.

[0004] When in use, this structure uses a shock-absorbing plate to absorb shocks and prevent damage to the internal parts from violent impacts. The wear-resistant protective layer at the lower end of the hammer head protects the hammer head. However, the hammer head is square, which makes it difficult to concentrate the force on one point when hammering. Furthermore, the single wear-resistant layer is prone to peeling off after long-term use, resulting in poor wear resistance. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a wear-resistant hammer for a crusher, which aims to solve the problems mentioned in the background art.

[0006] This utility model provides the following technical solution: a wear-resistant hammer for a crusher, including a hammer handle, on which a reinforcing connecting component is provided;

[0007] The reinforcing connection assembly includes a hammer head body disposed at one end of the hammer handle, and a guide ramp is provided at one end of the hammer head body;

[0008] The guide slope is welded with a reinforced carbide wear-resistant plate, and a number of reinforced chromium carbide strips are fixedly installed on the reinforced carbide wear-resistant plate. A number of reinforced side abutments are installed on the outer side of the reinforced carbide wear-resistant plate. The shape of the multiple reinforced chromium carbide strips is set as wavy, and a slag discharge channel for slag discharge is formed between each two adjacent reinforced chromium carbide strips.

[0009] As can be seen, in the above technical solution, the guide slope allows the crushing force point to be located at a certain point when the hammer body rotates, making the crushing more targeted. Furthermore, the wear resistance of the guide slope and the hammer body is improved by the reinforced carbide wear-resistant plate and the reinforced chromium carbide strip. At the same time, the slag discharge channel formed between two adjacent reinforced chromium carbide strips also facilitates the discharge of crushed debris through the slag discharge channel, preventing debris from accumulating together and improving the chip removal capacity.

[0010] Optionally, in one possible implementation, a plurality of reinforcing welded parts are distributed at the end of the hammer handle facing the hammer head body, and the plurality of reinforcing welded parts are distributed circumferentially along the axis of the hammer handle, and each of the reinforcing welded parts is welded to the hammer handle and the hammer head body.

[0011] It can be seen that in the above technical solution, by strengthening the setting of the side abutment plate, the reinforced carbonized wear-resistant plate is positioned on the guide slope to prevent the reinforced carbonized wear-resistant plate from falling off, and to ensure the stability of the reinforced carbonized wear-resistant plate under force when the hammer body is crushing.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] By setting up reinforced connection components, the overall design is simple and the structure is reasonable compared with the existing technology. Through the corresponding cooperation of various structures, the guide ramp can make the crushing force point when the hammer body rotates be located at a certain point, making the crushing more targeted. Furthermore, the wear resistance of the guide ramp and the hammer body is improved by reinforced carbonized wear-resistant plates and reinforced carbonized chromium strips.

[0014] Meanwhile, the slag discharge channel formed between two adjacent reinforcing chromium carbide strips also facilitates the discharge of crushed debris through the slag discharge channel, preventing the debris from accumulating together and improving the chip removal capacity.

[0015] Furthermore, by reinforcing the side abutment plates, the reinforced carbonized wear-resistant plates are positioned on the guide slope to prevent them from falling off, thus ensuring the stability of the reinforced carbonized wear-resistant plates under stress when the hammer body is crushing.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] As attached Figures 1-4 The wear-resistant hammerhead of a crusher shown features a reinforced connecting component on the hammer handle 1 and a guide ramp 3 that allows the crushing force point to be located at a specific point when the hammerhead body 2 rotates, making the crushing more targeted. Furthermore, the reinforced carbonized wear-resistant plate 4 and reinforced chromium carbide strips 5 improve the wear resistance of the guide ramp 3 and the hammerhead body 2. Simultaneously, the slag discharge channel 8 formed between two adjacent reinforced chromium carbide strips 5 facilitates the discharge of crushed debris, preventing debris from accumulating and improving slag discharge capacity. Additionally, the reinforced side abutment plate 6 positions the reinforced carbonized wear-resistant plate 4 welded to the guide ramp 3, preventing it from falling off and ensuring the stability of the reinforced carbonized wear-resistant plate 4 under stress during crushing. The specific structural configuration of the components is as follows.

[0024] The reinforced connection assembly includes a hammer head body 2 disposed at one end of the hammer handle 1, and a guide ramp 3 is provided at one end of the hammer head body 2;

[0025] A reinforced carbide wear-resistant plate 4 is welded on the guide slope 3. Several reinforced chromium carbide strips 5 are fixedly installed on the reinforced carbide wear-resistant plate 4. Several reinforced side abutments 6 are installed on the outer side of the reinforced carbide wear-resistant plate 4. The shape of the multiple reinforced chromium carbide strips 5 is wavy, and a slag discharge channel 8 for slag discharge is formed between each two adjacent reinforced chromium carbide strips 5.

[0026] Several reinforcing welded parts 7 are distributed at the end of the hammer handle 1 facing the hammer head body 2. The multiple reinforcing welded parts 7 are distributed around the circumference of the axis of the hammer handle 1, and each reinforcing welded part 7 is welded to the hammer handle 1 and the hammer head body 2.

[0027] According to the above structure, when in use, the operator installs the device on the crusher via the hammer handle 1. The hammer handle 1 serves as the support point. During crushing, the hammer handle 1 and the hammer body 2 rotate. The guide slope 3 ensures that the force point of the crushing is located at a certain point when the hammer body 2 rotates, making the crushing more targeted. Furthermore, the wear resistance of the guide slope 3 and the hammer body 2 is improved by the reinforced carbide wear-resistant plate 4 and the reinforced chromium carbide strip 5. At the same time, the slag discharge channel 8 formed between two adjacent reinforced chromium carbide strips 5 also facilitates the discharge of crushed debris through the slag discharge channel 8, preventing debris from accumulating and improving the chip removal capacity.

[0028] Furthermore, by reinforcing the side abutment plate 6, the reinforced carbonized wear-resistant plate 4 is positioned on the guide slope 3 to prevent it from falling off, thus ensuring the stability of the reinforced carbonized wear-resistant plate 4 under stress when the hammer body 2 is crushing.

[0029] Unlike existing technologies, this application discloses a wear-resistant hammer for a crusher. The guide ramp 3 ensures that the force point for crushing during the rotation of the hammer body 2 is concentrated at a specific location, making the crushing process more targeted. Furthermore, the reinforced carbonized wear-resistant plate 4 and reinforced chromium carbide strips 5 improve the wear resistance of the guide ramp 3 and the hammer body 2. Simultaneously, the slag discharge channel 8 formed between two adjacent reinforced chromium carbide strips 5 facilitates the discharge of crushed debris, preventing debris from accumulating and improving slag removal capacity. Additionally, the reinforced side abutment plate 6 positions the reinforced carbonized wear-resistant plate 4 welded to the guide ramp 3, preventing it from detaching and ensuring the stability of the reinforced carbonized wear-resistant plate 4 under stress during crushing.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
